free area. Both flanged and recessed chan-

nel frame options can be selected along with

standard bird guard, insect screen and

weather cill accessories.

75mm PITCH LOUVRES

Series WG75 with its 16 SWG 75mm Pitch

Louvres represents the principle building

block for the Gilberts Louvre system. This

unit utilises a 75mm blade, a profile which is

equally suitable for both small and large

Louvre Panels, allowing for a balanced

appearance across a broad spectrum of

sizes. The increased strength and rigidity of

this blade over its 38mm counterpart com-

bined with its physical size advantage has

led to its use as the Design Basis for many

of our other Louvre Products including sin-

gle doors, double doors and louvre screens.

In line with the smaller Louvres this series

offers a high resistance to weather ingress

combined with a good 50% free and both

flanged and recessed channel frame options

38/75/100mm CONTINUOUS LOUVRES

CONTINUOUS LOUVREFor applications where larger Louvre assem-

blies are required such as for wall or rooftop

screening and ventilation applications our

Series WG38, 75 and 100 can be supplied

any size in multiple panels, purpose built to

assemble into a continuous Louvre Screen.

Despatched with all the necessary fixing

angles and bolts for their assembly the panels

can be banked both horizontally and vertically

and designed to incorporate additional fea-

tures such as:

● Internal/External Mitred Corners

● Dummy, Blanked and Active Sections

● Horizontal and Vertical Blade Sections

● Single and double Hinged Continuous

Appearance Doors

Unusual and irregular profiles can typically be

catered for with accurate face alignment pro-

vided by the pre-fixed assembly holes and

blade alignment pieces. Rear mounted

Mullion Supports are provided for additional

strength where required.

Our standard fixing and assembly details are

illustrated herein. The individuality and com-

plexity of continuous screening applications

will however require, in each case, the prepa-

ration of detailed manufacturing drawings to

ensure that the unit not only meets all the

clients requirements but is also easy to

assemble, install and fix on site. Our

Company has been specially tailored to pro-

vide this all inclusive service with:

● Initial Site Surveys to obtain

construction work details

● Preparation of detailed manufacturing

drawings in accordance with the

clients requirements and the results of

the initial Survey

● Final manufacture and appropriate

finishing to blend or contrast, as

required with the building structure

● Expert Site installation by our own

team of skilled engineers

In this way a thorough and trouble free instal-

lation can be insured and our Louvre Team

will be pleased to give any advice or guidance

you may require for a particular application.

FIXING DETAILS - FLANGE FRAMEEither Face Flange Fixing or Rear Mounted Angle

Brackets can be selected on Flange Border Units.

CONCEALED ANGLEThe Concealed Angle Assembly design provides for virtually invisi-

ble jointing between Louvre panels. Accurate blade alignment on

the face is insured by the support clips and pre-drilled assembly

holes. Provision for Louvre expansion can also be made by apply-

ing Compriband Sealing/Expansion between the angles.

(WG75 shown).

VERTICAL ASSEMBLYFor assembly of vertical panels a reversed angle feature is

utilised as illustrated. This provides for a invisible joint whilst

maintaining the correct blade pitch.

(WG75 shown).

EXPANSION JOINTSWhere Louvres are supplied for installation by others it is

advisable that Compriband seal is inserted at all joints.

Where Gilberts are installing the Louvres Compriband will

be fitted.

FIXING DETAILS - CHANNEL FRAMEFor WG38, 75 & 100 Series Fixing Angle Cleats can

be situated on the appropriate centres at the rear of

the Louvre Frame drilled suitable for Expansion Bolts

(up to size M8) into structure.

to suit fixing tolerances.

Cleats are available in 4 standard lengths;

50mm,100mm, 150mm & 250mm and will be supplied

in 3mm hot dipped galvanised mild steel. Unless other

wise stated 100mm lengths will be provided.
